cis-Aqua­bis­(di-2-pyridyl­amine-κ²N,N′)iodidomanganese(II) iodide

The asymmetric unit of the title compound, [MnI(C₁₀H₉N₃)₂(H₂O)]I, contains a cationic Mn^II complex and an I⁻ anion. In the complex, the Mn^II ion is six-coordinated in a considerably distorted cis-N₄IO octa­hedral environment defined by four N atoms of the two chelating di-2-pyridyl­amine (dpa) ligands, one I⁻ anion and one O atom of a water ligand. As a result of the different trans effects of the I, N and O atoms, the Mn—N bond trans to the I atom is slightly longer than the Mn—N bond trans to the N or O atoms. The dpa ligands are not planar, with dihedral angles between the two pyridine rings of 26.2 (4) and 26.5 (4)°. The complex cations are stacked in columns along the a axis and are linked to the anions by inter­molecular O—H...I and N—H...I hydrogen bonds.

S1. Comment

Cationic Mn^II complexes with the di-2-pyridylamine (dpa; C₁₀H₉N₃) ligand, such as [MnX(dpa)₂(H₂O)]ClO₄ (X = N₃^-, NCO^-), have been investigated previously (Bose et al., 2005).

The asymmetric unit of the title compound, [MnI(dpa)₂(H₂O)]I, consists of a cationic Mn^II complex and an I^- anion (Fig. 1). In the complex, the Mn^II ion is six-coordinated in a considerably distorted cis-N₄IO octahedral environment defined by four N atoms of the two chelating dpa ligands, one I^- anion and one O atom of a water ligand. The main contribution to the distortion is the tight N—Mn—N chelating angles (Table 1), which results in non-linear trans axes [N3—Mn1—N4 = 165.7 (2)° and O1—Mn1—N6 = 171.7 (2)°]. However, the apical I1—Mn1—N1 bond is almost linear with a bond angle of 177.61 (17)°. The Mn—N(dpa) bond lengths are somewhat different and longer than the Mn—O(H₂O) bond (Table 1). As a result of the different trans effects of the I, N and O atoms, the Mn1—N1 bond trans to the I atom is slightly longer than the Mn—N bond trans to the N or O atoms. In the crystal structure, the dpa ligands are not planar. The dihedral angles between the two pyridyl rings of dpa are 26.2 (4)° and 26.5 (4)°.

The complexes are stacked in columns along the a axis, and the component cations and anions are linked by intermolecular O—H···I and N—H···I hydrogen bonds (Fig. 2, Table 2). In the column, numerous inter- and intramolecular π-π interactions between the pyridyl rings are present, the shortest centroid-centroid distance being 3.728 (5) Å.

S2. Experimental

To a solution of di-2-pyridylamine (0.3432 g, 2.005 mmol) in acetone (50 ml) was added MnI₂ (0.3108 g, 1.007 mmol) and refluxed for 7 h. The formed precipitate was separated by filtration and washed with acetone, and dried at 323 K, to give a white powder (0.1571 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from an MeOH solution.

S3. Refinement

Carbon-bound H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.95 Å and U_iso(H) = 1.2U_eq(C)]. Nitrogen- and oxygen-bound H atoms were located from Fourier difference maps then allowed to ride on their parent atoms in the final cycles of refinement with N—H = 0.92 Å, O—H = 0.84 Å and U_iso(H) = 1.5 U_eq(N, O). The highest peak (1.01 e Å^-3) and the deepest hole (-1.13 e Å^-3) in the difference Fourier map are located 1.01 Å and 0.79 Å from the atoms C8 and I1, respectively.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
